K&N wrench-off oil filters were originally invented to able to withstand the extremely high oil pressures found in racing environments, but have become increasingly more common due to several key attributes including heavy-duty canisters to house the filter, a 1-inch nut for easy filter removal with a common garage tool and a pre-drilled hole for safety wires. Started in 1969, K&N has garnered a reputation for engineering the world’s finest filtration products for cars, trucks, SUVs, motorcycles, race vehicles, commercial vehicles and anything in-between.

"I only pay about $4 for mine at wal-mart, but as far as filtration, it's very hard to beat for the price. Not only will it not void your warranty but it ranked as one of the best oil filters for your Ford next to Mobil 1, K&N, and Puralator. Which by the way are easily double or triple the price of the Motorcraft filter. You can never go wrong with OEM."posted by: '04 Cobra Guy on May 24, 2010

"This is a good filter. Good idea to use while your vehicle is under warranty. I could not believe how much this website is charging for this filter. I can get the same exact one at walmart for less than $4.00. I can't understand why they are charging so much on this website. I have the same exact filter that I purchased at walmart sitting right in front of me and it is identical with the one here on the screen. The one I have even says made in usa, which is a shocker having purchased it at walmart."posted by: f-150 owner on July 27, 2009view all 2 reviews
